GENERAL DESCRIPTION

WARNING: The sunroof installed on the 145 is supplied in two version:

• INALFA
• WEBASTO

The operating logic is the same, as also the outside appearance (the WEBASTO sunroof can be distinguished by three notches on the front spoiler).

The WEBASTO version is composed of a single unit comprising the control unit, motor and switches; the INALFA version has separate components.

The sliding roof allows additional ventilation of the passenger compartment during warm weather and, when necessary, quick air changing, thereby increasing passenger comfort.

The mobile part of the roof comprises a plexiglass panel and an interior sliding blind which is concealed in the roof panel trim.

A double switch located next to the front ceiling light operates a motor in two different ways: in the first, the motor raises the panel to the "quarter light" position, in the second, it opens the panel while drawing back the blind.

When the roof is subsequently closed, the blind, which can also be operated manually, is "accompanied" for a short stretch by the panel moving forwards. (For further details see GROUP 70 - "BODY-SUNROOF").

The whole system is controlled electronically by a control unit which regulates the various functions. The sunroof can only be operated with the ignition key engaged.

FUNCTIONAL DESCRIPTION

The sunroof control system is supplied by a special relay I58, located in fusebox G1 for version "A" or "C", and outside for version "B". The line is protected by a special fuse: F20 of G1 for fusebox "A" or "C", and by the outside wander fuse G261 (20A) for fusebox "B". To sum up, the system is only turn-key supplied at pin 2 of connector G95m; pin 1 of the same connector supplies the reference earth.

WEBASTO Version:

The system is formed of a single functional unit which comprises:

• control unit N60;
• control switch B47;
• motor P24;
• stroke limit contact H51.

The control unit N60 receives the actuating signals from switch B47 (pin 2 and 5) and consequently operates the motor P24 (pin 4 and 8), taking into account any stroke limit signal received from switch H51 (pin 7 and 9).

INALFA version:

The control unit N60, supplied directly at pins 8 and 9, receives the actuating signals from switch B47 (pins 6, 7 and 10), and sends the command signals to the motor P24 (pins 4 and 5); the stroke limit switch H51 signals the control unit (pins 1, 2 and 3) the position of the sunroof stopping the motor when necessary.
